Our take on Master of Orion 3

The defining structure is a changing galaxy: each campaign generates a different layout while the chosen race navigates policy, exploration, construction, diplomacy, covert operations, and war.

What is Master of Orion 3?

Master of Orion 3 is a galactic strategy game centered on leading one of 16 races toward supremacy.

Players establish policies, explore the galaxy, construct developments, declare war, and negotiate with other powers. Espionage activities include disinformation, subterfuge, betrayal, subversion, and assassination as part of the struggle for victory. Each game uses dynamic galaxy generation, creating a different galactic layout for every session. The game also includes a storyline involving the Orion Sector and its inhabitants.
